Foil Insulation Rolls – Slimline Thermal Barriers for Space-Constrained Applications

Our Foil Insulation Rolls Collection features high-performance multifoil insulation systems designed to reflect radiant heat, reduce thermal bridging, and improve energy efficiency in buildings. These products are engineered for use in lofts, walls, roofs, and other areas where space is limited but thermal performance is critical.

Composition and Function

Foil insulation rolls are constructed from multiple layers of reflective foil, insulating wadding, and vapor control membranes. This multi-layered structure creates a radiant barrier that reflects heat back into the building during winter and deflects solar gain during summer. The result is improved thermal comfort and reduced energy consumption year-round.

Unlike bulkier insulation types, multifoil insulation offers high thermal resistance in a compact profile. It is particularly effective when used in combination with other insulation systems, enhancing overall U-value performance without adding significant thickness.

Product Features

• Multi-layered construction with reflective foil surfaces
• Available in standard roll widths and lengths for easy handling
• Lightweight and flexible for quick installation
• Suitable for retrofit and new-build projects
• Compatible with timber, masonry, and metal frame systems

Applications

• Loft conversions and pitched roof insulation
• Timber frame and stud wall systems
• Underfloor insulation in suspended floors
• Garden rooms, modular buildings, and caravans
• Vapour control and thermal bridging reduction in hybrid systems

Performance Benefits

• Reflects up to 95% of radiant heat
• Reduces heat loss and improves thermal envelope performance
• Slim profile saves space in confined areas
• Helps meet Part L Building Regulations for energy efficiency
• Long lifespan with minimal maintenance requirements

Installation and Handling

Foil insulation rolls are easy to cut, staple, or tape into position. They can be installed horizontally or vertically, and are often used in combination with battens or counter-batten systems to create air gaps that enhance thermal performance. Many products in this category are certified for use in UK construction and meet relevant fire, moisture, and durability standards.
